Dr. David Perlmutter, author of best-selling Grain Brainand a board-certified neurologist, explains how germ theory—the idea that germs are mostly bad and cause disease—was fundamentally wrong. Most germs are good for you! In fact, you're surrounded by a bubble of bacteria that is unique to you and your body—the microbiome doesn't stop at the gut. Watch his interview with mindbodygreen Founder and CEO Jason Wachob to learn more about how our microbiomes communicate on our behalf, and how they've been doing so since birth.

Dr. Perlmutter is a trusted source when it comes to gut health. In his most recent book, Brain Maker, he dives deeper into the role of the microbiome in our health. With degenerative and cognitive-based diseases on the rise from autism and ADHD in children to Parkinson's and Alzheimer's in adults, uncovering the nuances in the relationship between the brain and the gut has never been more important.
